    目的:胃癌(GC)是全球癌症死亡的第三大原因。将上消化道内窥镜检查(UGIE)与结肠镜检查相结合的筛查策略在中等风险区域可能具有成本效益。本研究旨在评估坚持联合内镜筛查的意图,并评估GC症状的知识。危险因素,和筛选的障碍。
    方法:在葡萄牙北部招募符合CRC筛查资格的个体的横断面研究,其中实施了人口粪便隐血测试(FOBT)程序。经过验证的PERCEPT-PREVENT工具应用于三组:(a)尚未邀请CRC筛查,(B)FOBT阳性转归结肠镜检查,和(c)原发性结肠镜检查筛查。
    结果:观察到联合内镜筛查的接受率高(94%;n=264)[尚未邀请进行CRC筛查98%(n=90)与FOBT阳性涉及结肠镜检查90%(n=103)与原发性结肠镜检查97%(n=71);p=0.017],绝大多数报告者打算坚持全额报销(97%;n=255)。大多数受访者不知道任何可能的GC症状(76%;n=213),危险因素(73%;n=205),和UGIE相关并发症(85%;n=237)。与初级保健医生定期随访(赔率比(OR)27.59,95%置信区间(CI)2.99-254.57),UGIE的感知负面健康后果较低(OR1.40,95%CI1.13-1.74),和较低的经济负担(OR2.46,95%CI1.04-5.85)是与较高的联合筛查意向独立相关的唯一因素.
    结论:接受联合内镜筛查的意愿明显较高,并受到较低的感知障碍的积极影响。应进一步努力提高消化系统健康素养水平。
    OBJECTIVE: Gastric cancer (GC) is the third cause of cancer mortality worldwide. A screening strategy that combines an upper gastrointestinal endoscopy (UGIE) with a screening colonoscopy may be cost-effective in intermediate-risk regions. This study aimed to evaluate the intention to adhere to combined endoscopic screening and assess knowledge of GC symptoms, risk factors, and barriers to screening.
    METHODS: Cross-sectional study enrolling individuals eligible for CRC screening in northern Portugal, where a populational fecal occult blood test (FOBT) program is implemented. The validated PERCEPT-PREVENT tool was applied across three groups: (a) not yet invited to CRC screening, (b) FOBT-positive referred to colonoscopy, and (c) primary colonoscopy screening.
    RESULTS: A high acceptance rate was observed for combined endoscopic screening (94%; n = 264) [not yet invited to CRC screening 98% (n = 90) vs. FOBT-positive referred to colonoscopy 90% (n = 103) vs. primary colonoscopy 97% (n = 71); p = 0.017], with the vast majority reporting intention to adhere in the setting of full reimbursement (97%; n = 255). Most respondents were unaware of any possible GC symptom (76%; n = 213), risk factor (73%; n = 205), and UGIE-related complication (85%; n = 237). Regular follow-up with the primary care physician (Odds Ratio (OR) 27.59, 95% confidence interval (CI) 2.99-254.57), lower perceived negative health consequences of UGIE (OR 1.40, 95% CI 1.13-1.74), and lower perceived financial burden (OR 2.46, 95% CI 1.04-5.85) were the only factors independently associated with a higher intention to undergo combined screening.
    CONCLUSIONS: Willingness to undergo combined endoscopic screening was notably high and positively impacted by lower perceived barriers. Additional efforts should be undertaken to improve levels of digestive health literacy.

    背景:宫颈癌发病率和死亡率在佛得角排名第三。了解与宫颈癌筛查(CCS)年龄相关的因素至关重要,因为它有助于识别有延迟筛查风险的人群。能够进行有针对性的干预,以确保及时发现和治疗,最终减轻宫颈癌的负担。我们研究了佛得角成年女性首次筛查宫颈癌时与年龄相关的因素。
    方法:使用来自2020年WHOSTEP调查的数据。我们分析了1,082名30-69岁女性的数据,这些女性曾经筛查过宫颈癌。在STATA第18版中计算了双变量和多变量逻辑回归模型。
    结果:总体而言,研究中,有30.6%的女性在30岁之前或30岁时患有首次CCS。除了在过去12个月内访问医疗机构外,在粗模型中,所有变量均显着预测女性的CCS第一年龄。在调整后的模型中,与没有接受过正规教育的女性相比,接受过高等教育的女性显示出更大的几率[AORs=9.85;95%CI:4.12-23.54].与那些从未结过婚的人相比,既往已婚女性早期筛查的几率显著较低[AOR=0.63;95%CI:0.39~0.99].与高血压患者相比,没有高血压的女性早期筛查的几率更高[AOR=1.66;95%CI:1.18-2.34]。此外,目前工作的女性早期筛查的几率显著高于失业的女性[AOR=1.49;95%CI:1.09-2.04].
    结论:结论:实施有针对性的教育运动,解决社会经济障碍,将宫颈癌筛查纳入常规医疗保健服务可以提高佛得角妇女的早期筛查率。有必要将CCS纳入高血压妇女的常规医疗保健服务中。此外,正规教育和初筛年龄之间的正相关,佛得角公共卫生部门必须在学校内实施全面的教育计划,以提高对CCS的认识。
    BACKGROUND: Cervical cancer ranks third in terms of cancer incidence and mortality in Cape Verde. Understanding the factors associated with the age of cervical cancer screening (CCS) is essential because it helps identify populations at risk of delayed screening, enabling targeted interventions to ensure timely detection and treatment, ultimately reducing the burden of cervical cancer. We examined the factors associated with age at first screening for cervical cancer among adult Cape Verdean women.
    METHODS: Data from the 2020 WHO STEPs survey were used. We analyzed data from 1,082 women aged 30-69 years who had ever screened for cervical cancer. Bivariable and multivariable logistic regression models were computed in STATA version 18.
    RESULTS: Overall, 30.6% of women in the study had their first CCS before or at age 30. Except for visits to the health facility within the last 12 months, all variables significantly predicted women\'s first age for CCS in the crude model. In the adjusted model, women with tertiary education showed greater odds [AORs = 9.85; 95% CI: 4.12-23.54] compared to those with no formal education. Compared to those who were never married, previously married women had significantly lower odds of screening at an early age [AOR = 0.63; 95% CI: 0.39-0.99]. Women without hypertension had higher odds [AOR = 1.66; 95% CI: 1.18-2.34] of early screening compared to those with hypertension. Also, women who were currently working had significantly higher odds of early screening than those unemployed [AOR = 1.49; 95% CI: 1.09-2.04].
    CONCLUSIONS: In conclusion, implementing targeted educational campaigns, addressing socio-economic barriers, and integrating cervical cancer screening into routine healthcare services can increase the early screening uptake among Cape Verdean women. There is a need to integrate CCS in the routine healthcare services of women living with hypertension. Also, the positive association between formal education and age at first screening, it is imperative for the Cape Verdean public health departments to implement comprehensive education programs within schools to promote awareness about CCS.

    目的:回顾运动干预对运动相关脑震荡(SRC)发生率的影响,以及线性和旋转头部加速度,和等距颈部力量,并使用运动报告模板共识(CERT)评估运动干预措施的报告完整性。
    方法:系统评价和荟萃分析,根据《锻炼中的棱镜》,康复,运动医学和孢子科学指南。
    方法:六个数据库(MEDLINE,Embase,CINAHL,Scopus,WebofScienceCC和SPORTDiscus)进行了搜索,直到2023年6月26日。
    方法:随机对照试验(RCT),集群随机对照试验或准实验研究,评估运动干预对SRC发病率的影响,线性和旋转头部加速度,和/或任何年龄的男性和/或女性运动员的等距颈部力量,和/或在健康的普通人群中。
    结果:共纳入26篇。阻力训练(RT)对等距颈部力量的影响很大(标准化平均差(SMD)0.85;95%CI0.57至1.13;高质量证据)。神经肌肉热身计划对SRC发生率的影响不显著(风险比0.69;95%CI0.39至1.23;低质量证据),或对于头部线性加速度(SMD-0.43;95%CI-1.26至0.40;极低质量证据)或头部旋转加速度(SMD0.08;95%CI-0.61至0.77;低质量证据)。没有研究评估RT对SRC发生率的影响。CERT评分范围从4到16(共19分),中位数为11.5(IQR9-13)。
    结论:RT增加了等距颈部强度,但对SRC发病率的影响尚不清楚。需要更充分和严格的试验来评估运动干预对SRC发生率的影响。以及线性和旋转头部加速度。未来的研究应遵循CERT指南,因为纳入的干预措施通常没有足够详细地报告,无法准确复制.

    OBJECTIVE: To review the efficacy of exercise interventions on sport-related concussion (SRC) incidence, as well as on linear and rotational head accelerations, and isometric neck strength and to assess reporting completeness of exercise interventions using the Consensus on Exercise Reporting Template (CERT).
    METHODS: Systematic review and meta-analysis, according to the Prisma in Exercise, Rehabilitation, Sport medicine and SporTs science guidelines.
    METHODS: Six databases (MEDLINE, Embase, CINAHL, Scopus, Web of Science CC and SPORTDiscus) were searched up to 26 June 2023.
    METHODS: Randomised controlled trials (RCTs), cluster RCTs or quasi-experimental studies, evaluating exercise interventions on SRC incidence, linear and rotational head accelerations, and/or isometric neck strength in male and/or female athletes of any age, and/or in a healthy general population.
    RESULTS: A total of 26 articles were included. A large effect size was observed for resistance training (RT) on isometric neck strength (standardised mean difference (SMD) 0.85; 95% CI 0.57 to 1.13; high-quality evidence). Non-significant effect sizes were observed for neuromuscular warm-up programmes on SRC incidence (risk ratio 0.69; 95% CI 0.39 to 1.23; low-quality evidence), or for RT on linear head acceleration (SMD -0.43; 95% CI -1.26 to 0.40; very low-quality evidence) or rotational head acceleration (SMD 0.08; 95% CI -0.61 to 0.77; low-quality evidence). No studies assessed the impact of RT on SRC incidence. CERT scores ranged from 4 to 16 (out of 19) with median score of 11.5 (IQR 9-13).
    CONCLUSIONS: RT increases isometric neck strength, but the effect on SRC incidence is unknown. More adequately powered and rigorous trials are needed to evaluate the effect of exercise interventions on SRC incidence, and on linear and rotational head accelerations. Future studies should follow CERT guidelines, as the included interventions were generally not reported in sufficient detail for accurate replication.

    心血管预防策略以癌症队列中有效性未知的风险评分为指导。
    这项研究旨在评估来自英国生物银行的癌症幸存者中7个已建立的心血管风险评分的预测性能。
    QRISK3,系统性冠状动脉风险评估2(SCORE2)/老年人系统性冠状动脉风险评估(SCORE-OP)的预测性能,弗雷明汉风险评分,预防心力衰竭的集合队列方程(PCP-HF),CHARGE-AF,QStroke,和CHA2DS2-VASc在有和无癌症史的参与者中计算。参与者在年龄上倾向匹配,性别,剥夺,健康行为,家族史,和代谢条件。分析被分层为任何癌症,乳房,肺,前列腺,大脑/中枢神经系统,恶性血液病,霍奇金淋巴瘤,和非霍奇金淋巴瘤.在10年的随访中,通过健康记录链接跟踪心血管事件。接收器工作曲线下的面积,平衡精度,报告了敏感性。
    分析包括31,534名癌症幸存者和126,136个协变量匹配的对照。病例和对照的风险评分分布几乎相同。患有任何癌症的参与者在所有心血管疾病结局中的发生率均明显高于匹配的对照组。在癌症病例中,所有风险评分的表现指标都明显差于匹配的对照。最显着的差异是有血液系统恶性肿瘤病史的参与者,其结局率明显高于对照组,风险评分表现较差。预测脑/中枢神经系统癌症参与者中风的风险评分表现非常差,预测准确性比非癌症对照低30%以上。
    现有的心血管风险评分与非癌症对照者相比,癌症幸存者的预测准确性明显更差,导致该队列中风险的低估。
    UNASSIGNED: Cardiovascular preventive strategies are guided by risk scores with unknown validity in cancer cohorts.
    UNASSIGNED: This study aimed to evaluate the predictive performance of 7 established cardiovascular risk scores in cancer survivors from the UK Biobank.
    UNASSIGNED: The predictive performance of QRISK3, Systematic Coronary Risk Evaluation 2 (SCORE2)/Systematic Coronary Risk Evaluation for Older Persons (SCORE-OP), Framingham Risk Score, Pooled Cohort equations to Prevent Heart Failure (PCP-HF), CHARGE-AF, QStroke, and CHA2DS2-VASc was calculated in participants with and without a history of cancer. Participants were propensity matched on age, sex, deprivation, health behaviors, family history, and metabolic conditions. Analyses were stratified into any cancer, breast, lung, prostate, brain/central nervous system, hematologic malignancies, Hodgkin lymphoma, and non-Hodgkin lymphoma. Incident cardiovascular events were tracked through health record linkage over 10 years of follow-up. The area under the receiver operating curve, balanced accuracy, and sensitivity were reported.
    UNASSIGNED: The analysis included 31,534 cancer survivors and 126,136 covariate-matched controls. Risk score distributions were near identical in cases and controls. Participants with any cancer had a significantly higher incidence of all cardiovascular outcomes than matched controls. Performance metrics were significantly worse for all risk scores in cancer cases than in matched controls. The most notable differences were among participants with a history of hematologic malignancies who had significantly higher outcome rates and poorer risk score performance than their matched controls. The performance of risk scores for predicting stroke in participants with brain/central nervous system cancer was very poor, with predictive accuracy more than 30% lower than noncancer controls.
    UNASSIGNED: Existing cardiovascular risk scores have significantly worse predictive accuracy in cancer survivors compared with noncancer comparators, leading to an underestimation of risk in this cohort.

    背景:本研究的伦理批准已由阿德莱德中央地方卫生网络(HREC2022/HRE00284)提供。该研究的招聘始于2023年6月,并将持续到2024年7月。这些方法已根据SPIRIT和CONSORT试点研究清单进行了设计和报告。
    背景:澳大利亚新西兰临床试验注册中心(ANZCTR):ACTRN12623000052639。
    BACKGROUND: Assessing multidisciplinary prehabilitation strategies becomes crucial to pre-emptively counter the physical, psychological and social negative impacts experienced during an allogenic haematopoietic stem cell transplant (allo-HSCT) among acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) patients. Current evidence is restricted to studies during induction chemotherapy, omitting rehabilitation interventions and predominantly using exercise-only approaches without a multidisciplinary framework. The aim of this study is to investigate the feasibility, safety and preliminary efficacy of multidisciplinary prehabilitation in adults offered allo-HSCT.
    METHODS: This 8-week single-group pre-post feasibility study aims to pilot a multidisciplinary prehabilitation intervention for participants undergoing allo-HSCT, with a focus on feasibility and safety. Participants, aged 18 or older, diagnosed with AML or MDS, and offered allo-HSCT, will be recruited between June 2023 and July 2024. The multidisciplinary prehabilitation intervention, conducted by the cancer allied health team at the Royal Adelaide Hospital, includes exercise physiology, physiotherapy, dietetics, social work, occupational therapy and psychology interventions. Consistent with a multidisciplinary treatment approach, each component is tailored to address different aspects of patient care, and adherence calculations will assess patient engagement and compliance. In addition, participants will continue to receive usual care from cancer allied health staff. The primary outcome of the study is to assess the feasibility of a multidisciplinary prehabilitation intervention by evaluating intervention uptake, retention, adherence, acceptability and safety. Secondary outcomes are leg strength, upper-body strength, aerobic fitness, falls risk, anthropometry, nutritional status, quality of life, anxiety, depression, self-efficacy for coping with cancer and distress.
    BACKGROUND: Ethics approval for this study has been provided by the Central Adelaide Local Health Network (HREC 2022/HRE00284). Recruitment for the study commenced in June 2023 and will continue until July 2024. The methods have been designed and are reported according to the SPIRIT and CONSORT-pilot study checklist.

    目的:探索急诊医疗服务(EMS)检测心房颤动(AF)的可接受性和可行性,并确定潜在的障碍和促进因素,以实施正式途径,以促进初级保健的随访,这可以降低房颤相关卒中的风险。
    方法:定性研究使用焦点小组和以半结构化主题指南为指导的一对一访谈。
    方法:英格兰东北部。
    方法:由18名公众组成的焦点小组,并与11名医疗保健和服务提供商进行一对一的在线访谈(6名护理人员和5名代表心脏病学的专家,全科医生(GP),公共卫生,研究,政策和调试)。
    结果:所有参与者组都支持EMS在确定AF作为常规评估的一部分和对AF检测反应的正式化中的作用。然而,这不应该给EMS造成延误,因为速率控制的AF是非紧急的,并且存在其他社区机制来管理它。公众参与者关注房颤诊断的沟通,以及是否应该“现场”或随后的全科医生预约。护理人员报告经常偶然发现房颤,但它并不总是清楚\'现场\',这是一个新的诊断,并且在实践中存在关于是否(以及如何)将其传达给GP的差异。护理人员还专注于确保未传达患者的安全以及对“主动”报告流程的感知需求,所以AF的发现被采取行动了。现场专家认为,正式的途径将是有用的,并且有利于简单的干预,而不会不必要地增加时间压力。
    结论:支持开发正式途径以确保对EMS偶然发现的房颤患者进行随访。这有可能提高抗凝率并降低中风的风险。
    OBJECTIVE: To explore the acceptability and feasibility of detection of atrial fibrillation (AF) by emergency medical services (EMS) and identify potential barriers and facilitators to implementing a formal pathway to facilitate follow-up in primary care, which could reduce the risk of AF-related stroke.
    METHODS: Qualitative study using focus groups and one-to-one interviews guided by a semistructured topic guide.
    METHODS: North East England.
    METHODS: Focus groups with 18 members of the public and one-to-one online interviews with 11 healthcare and service providers (six paramedics and five experts representing cardiology, general practice (GP), public health, research, policy and commissioning).
    RESULTS: All participant groups were supportive of a role of EMS in identifying AF as part of routine assessment and formalising the response to AF detection. However, this should not create delays for EMS since rate-controlled AF is non-urgent and alternative community mechanisms exist to manage it. Public participants were concerned about communication of the AF diagnosis and whether this should be \'on scene\' or in a subsequent GP appointment. Paramedics reported frequent incidental identification of AF, but it is not always clear \'on scene\' that this is a new diagnosis, and there is variation in practice regarding whether (and how) this is communicated to the GP. Paramedics also focused on ensuring the safety of non-conveyed patients and a perceived need for an \'active\' reporting process, so that a finding of AF was actioned. Field experts felt that a formal pathway would be useful and favoured a simple intervention without adding to time pressures unnecessarily.
    CONCLUSIONS: There is support for the development of a formal pathway to ensure follow-up for people with AF that is incidentally detected by EMS. This has the potential to improve anticoagulation rates and reduce the risk of stroke.

    目的:研究人员将Lindsay-Dennis的黑人女性主义-女性主义研究范式应用于Andersen的健康服务行为模型,以指导有关美国黑人女性预防健康行为的初步研究。
    方法:本文重点介绍了此应用程序,使用解释性现象学分析对定性问题进行评估,以评估40名黑人女大学生如何定义健康及其在医疗保健方面的经验。这是2022年横截面在线调查中更大的聚合并行混合方法方法的一部分。
    结果:参与者将健康定义为涉及健康素养的概念,身心健康,没有健康状况或疾病。关于健康相关的生活经历,负面经验的报告频率高于正面经验.然而,许多参与者报告了积极和消极的医疗保健相关经历.易感,启用,和需求因素都存在于定性响应中。
    结论:本文强调了黑人女权主义者-女性主义者研究范式与安徒生模型的契合,以更好地了解黑人女性的健康经历,并说明了医学上不信任的方式,健康素养,过去的医疗保健经验会影响医疗服务的使用。还讨论了有关预防保健障碍和促进者的未来研究领域以及对减少健康差异的影响。
    OBJECTIVE: The researchers applied Lindsay-Dennis\' Black Feminist-Womanist research paradigm to Andersen\'s Behavioral Model for Health Service Use to guide initial research about Black American women\'s preventive health behaviors.
    METHODS: This article highlights this application, using interpretive phenomenological analysis for qualitative questions assessing how 40 Black college women define health and their experiences in health care. This was part of a larger convergent parallel mixed-methods approach in a 2022 cross-sectional online survey.
    RESULTS: Participants defined health as a concept involving health literacy, physical and mental health, and being free from health conditions or disease. Regarding health-related lived experiences, negative experiences were more frequently reported than positive experiences. However, many participants reported both positive and negative health care related experiences. Predisposing, enabling, and need factors were all present in qualitative responses.
    CONCLUSIONS: This article highlights the fit of a Black Feminist-Womanist research paradigm to Andersen\'s model to better understand Black women\'s health experiences and illustrates ways that medical mistrust, health literacy, and past experiences with health care can influence health service use. Areas for future research on barriers and facilitators to preventive care and implications for reducing health disparities are also discussed.

    阿尔茨海默病(AD)仍然是全球范围内痴呆症的广泛原因,由于人口老龄化,其患病率正在增加。两种关键病理通常确定这种神经退行性疾病过程:淀粉样蛋白斑的积累和含有过度磷酸化tau的神经原纤维缠结的形成。诊断依赖于患者的临床表现符合特定标准,以及流体和成像生物标志物的使用。目前的治疗重点是解决症状,正在进行的试验旨在减少脑病理学的产生和整体影响。这里,我们探索了各种方法来最大限度地降低患者和高危患者患AD的风险.为了解决这个问题,我们精心挑选了10篇文章,讨论了今天用来促进大脑健康的各种预防方法,包括被认为具有神经保护特性的饮食。研究结果强调了进一步加强证据和进行更大规模的随机对照试验的重要性,以更好地了解患有AD的高风险个体的潜在益处。以及那些已经被诊断出患有这种疾病的人。
    Alzheimer\'s disease (AD) remains a widespread cause of dementia globally, and its prevalence is increasing due to the aging population. Two key pathologies typically identify this neurodegenerative disease process: the accumulation of amyloid plaques and the formation of neurofibrillary tangles containing hyperphosphorylated tau. Diagnosis relies on the patient\'s clinical presentation meeting specific criteria, along with the use of fluid and imaging biomarkers. The current treatment focuses on addressing symptoms, with ongoing trials aiming to decrease the production and overall impact of brain pathology. Here, we explore various methods to minimize the risks of AD in patients and individuals at high risk of developing it. To address this, we carefully selected 10 articles that discuss various prevention methods used today to promote brain health, including diets that are believed to have neuroprotective properties. The study findings emphasize the importance of further strengthening the evidence and conducting larger randomized controlled trials to gain a better understanding of the potential benefits for individuals at high risk of developing AD, as well as those already diagnosed with it.

    目的:尿液比重(USG)是估算猫尿液浓度的最常用方法。如果在具有较高诊断价值的环境中战略性地使用USG作为筛查工具,则易于获得,并且对客户而言成本较低。目前,关于USG如何在猫中随年龄变化的人口信息很少。
    方法:从1000多家医院的电子宠物医疗记录中收集数据,并筛选出临床状态明显健康且诊断信息完整的猫。在多项分析中将USG与年龄进行比较,以检查变量之间的关系。
    结果:在没有其他疾病指标的情况下,肾脏浓缩能力开始减弱,平均而言,从大约9岁开始。按年龄组,与1岁以下的猫相比,11-15岁的猫(1.044,95%置信区间[CI]1.043-1.044)的平均USG明显较低(1.049,95%CI1.048-1.051;P<0.001),1-6年(1.049,95%CI1.049-1.050;P<0.001)或7-10年(1.049,95%CI1.048-1.049;P<0.001)。与年龄小于1年的猫相比,年龄为15岁的猫(1.038,95%CI1.036-1.040)的平均USG在统计学上显着降低(P<0.001),1-6年(P<0.001),7-10年(P<0.001)或11-15年(P<0.001)。
    结论:肾脏浓缩能力开始减弱,平均而言,从大约9岁开始,随着猫年龄的增加而逐渐增加。这项研究提供了重要的新信息,以帮助改善猫集中能力障碍的筛查方法。
    OBJECTIVE: Urine specific gravity (USG) is the most common method for the estimation of urine concentration in cats. Utilization of USG as a screening tool is easily accessible and is of low cost to the client if strategically utilized in settings of higher diagnostic value. There is currently minimal population information regarding how USG changes across ages in cats.
    METHODS: Data were collected from electronic pet medical records from more than 1000 hospitals and screened for cats with an apparently healthy clinical status and complete diagnostic information. USG was compared with age in multiple analyses to examine the relationship between the variables.
    RESULTS: In the absence of other indicators of disease, renal concentrating ability begins to diminish, on average, starting at approximately 9 years of age. By age group, cats aged 11-15 years (1.044, 95% confidence interval [CI] 1.043-1.044) had statistically significantly lower mean USGs compared with cats aged less than 1 year (1.049, 95% CI 1.048-1.051; P <0.001), 1-6 years (1.049, 95% CI 1.049-1.050; P <0.001) or 7-10 years (1.049, 95% CI 1.048-1.049; P <0.001). Cats aged ⩾15 years (1.038, 95% CI 1.036-1.040) had statistically significantly lower mean USGs compared with cats aged less than 1 year (P <0.001), 1-6 years (P <0.001), 7-10 years (P <0.001) or 11-15 years (P <0.001).
    CONCLUSIONS: Renal concentrating ability begins to diminish, on average, starting at approximately 9 years of age and is progressive as cat age increases. This study provides important and new information to help improve screening practices for disorders of concentrating ability in cats.
